Module Guide

Multifunctional Interface Modules (Router 5000)

The synchronous serial interface can work in either DTE or DCE mode. Two directly connected devices must work as DTE and DCE respectively. The DCE provides clock synchronization and specifies the communication rate, whereas the DTE accepts clock synchronization and communicates at the specified rate.

The router normally works as a DTE. To identify whether the equipment connected to the router is DTE or DCE, refer to the manual shipped with the equipment.

II.Speed and transmission segment of synchronous/asynchronous serial interface

In different operating modes, the synchronous/asynchronous serial interface supports different electric signal specifications and baud rates. In addition, the maximum signal transmission segment depends not only on the specified baud rate but also on the selected cable. The following table shows how the cable type, baud rate, and the maximum signal transmission segment related to each other.
